SPECIFICATION forming part of Letters Patent No. 448,025, dated December 16, 1890.

Application filed August 6, 1890. Serial No. 361,206- (No model.)

To all whom it may concern:

Be it known that I, CARL V. VEISS, of

Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Adding and Registering Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the a'ccompanying drawings, and t the letters and figures of reference marked thereon, making a part of this specification.

. My invention relates to that class of indicating, adding, and registering machines in which the drivingi'nechanism and the adding mechanism are connected or disconnected by means of devices brought into play by the adjustment of the device indicating the n u inher to be added.

It has for its object to simplify the same and to increase the eliiciency thereof; and it consists in the novel combination and arrangement of arts to attain the desired result,

' substantially as is hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation, partly in section, of a portion of the stop-indicator, indicating-dial, and operating-crank of a machine embodying my invention, the casing not beingshown and the front plate being partly broken away to disclose the adjustable stops and the operatingcrank. Fig.2 is a side elevation of themechanism shown in Fig. 1, looking to the right, with the casingin section. Fig. Sis a detail in perspective of the clutch mechanism by which the adding mechanism is automatically coupled with and uncoupled from the driving mechanism. Fig. 4 is a detail in elevation illustrating a modification in the form and construction of the stop device. Fig. 5 is a side elevation of the same with the casing in section. Fig. 6 is a detail in elevation, partly broken away, illustrating a modification of my invention, Fig. 7 being a transverse section thereof in line at a; of Fig. 6.

Similar letters and figures indicate like parts in all of the figures.

In working out myinvention the necessary indication, first, of the number to be added or registered, and, second, of the same numberaftcr it has been added or registered, may

be produced either by means of a dial hearing the numbers and which is free to revolve undera fixed pointer or by means of a pointer revolving over a fixed dial bearing the numbers.

In the accompanying drawings, A represents a dial bearing upon its face figures corresponding with the series of numbers in 0011- nection with which the machine is to be used. This dial is secured upon a central pivot B, mounted to turn in. the front plate C of the case of the machine so as to revolve with said pivot B, under a pointer D, fixed to the casing to overhang the circular rim of the dial. The outer end of the pivot 13 is fitted with a knob E, by which it may be readily turned, and upon its inner end is made fast a radial arm F, carrying upon its outerend a frictionroller 71. By rotating the pivot B the friction- 7o roller h is brought successively into contact with the inner ends of a series of radial rods or stops G G G, corresponding in number with .the figures on the dial A, and which are mounted at equal distances apart to have longitudinal playparallel with the face of the dial in two concentric flanges a a, projecting inward from the front plate 0 of the casing about'the pivot B as a center. The inner end of each rod G is beveled or formed with So a beveled head 0, whereby when the frlctionroller h is brought into contact therewith from either direction it will pass under the end of the rod and force the rod outwardly so that its outer end shall project beyond the outer concentric flange a, through which it plays. Each rod is encircled by a spiralspring 1), bearing against one of the concen trio flanges, and operating automatically to carry the rod inward when free, its inward 9o movement being limited by a transverse pin 6. The rods G G are so disposed with reference to the pointer D as that when any one number on the dial is brought under said pointer the friction-roller h shall be carried 5 under the rod corresponding with said numher, and having forced it outward will hold it in its outward position until another move is made with the dial.

The train of adding and registering wheels :00 for the machine, of which the units-wheel II is alone shown in the drawings, (see Fig. 2;)

is mounted upon a shaft H, whose axis is preferably made to coincide with that of the pivot 13 for the stop-indicator dial A, as shown in Fig. 2, and whose outer end is extended into close proximity to the front plate of the case. The units-wheel H is pinned to said shaft. A hub I and a disk J having a lateral pinion J formed integral therewith or rigidly secured thereto, are journaled to revolve freely andindependently upon said outer end of the shaft, and a ratchet-wheel K, of a diameter corresponding with that of the disk J, is mounted upon the shaft and pinned thereto intermediate the disk and hub.

An arm I is made to extend radially from the huh I and furnishes a bearing fora transverse rod L, (see Fig. 3,) pivoted in the outer end of the arm to extend parallel with the shaft H over the ratchet-wheel K and disk J. To this red L is made fast a dog or clutch device M, in position to rest upon the periphery of the disk J and to drop into a single notch m in said periphery, (see Fig. 3,) while upon the same rod a pawl N is loosely pivoted to engage the teeth of the ratchet-wheel K, the said teeth being so inclined as that when the pawl is revolved about the wheel in one direction it will glide freely over them; but in a reverse movement the pawl will engage the same and carry the wheel with it. Both the clutch-dog M and pawl N are actuated by springs 0 0, attached to a fixed pin f, extending parallel with a pivoted rod L from an offset g in the end of the arm I, as shown in Fig. 3. A pointer P is made fast to the inner end of the rod L, so that it will revolve with the arm 1 carrying said rod about the shaft 11 as a center,- and so far as the spring 0, governing the dog M, fixed to the rod L, will permit, this pointer admits of an independent vibration upon said rod as a pivotal center. A dial Q is mounted under the pointer, (see Fig. 1,) said dial having figures thereon corresponding with the revolving dial A of the stop-indicator, and the pointer is made to describe a complete circle back and forth over the dial by means of a crank R upon a rock-shaft R, carrying an arm R fitted at its outer end with a toothed segment R gearing with the lateral pinion J on the disk J. The movement of the crank R is so limited and its gear with the pinion J so adjusted as that in making a complete stroke to the right or the left it will produce a single complete revolution of the pinion. A reverse movement of the crank after it has commenced to move in either direction before it has completed its stroke in that direction is prevented in the customary manner by a double-aeting spring-aetuated detent S, (see Fig. 1,) engaging a toothed segment S, fitted on the crank. The revolution of the pinion J and its disk J will, by reason of the engagement of the dog M, fixed upon the rod L, carried by the arm 1', to which the pointer P is attached, produce a corresponding revolution of the pointer, and by means of the engagement of the pawl N, likewise carried by the rod L, with the' ratchet-wheel K the shaft H and adding mechanism II will be made to revolve in unison with the pointer in its forward movement so long as the dog M remains in engagement with the disk J.

A carrier '1 is fixed to the arm I, carrying the pointer I, so as to travel with it, and upon this carrier is pivoted a detent U in position to overhang and ride upon the outer concentric flange a, through which the radial stops G G play. The detent U is so inclined as that when the pointer P is making a reverse or backward movement the pawl will ride freely over the end of either of the steps which may be projecting out through the flange a; but when the pointer is traveling forward the engagement of the pawl with the stop will produce a lock, and thereby arrest the further movement of the pointer. hen this occurs, the continued strain of the driving mechanism upon the arm I, carrying the pointer P, will cause the pointer and its pivot-pin L to turn upon the axis of said pin, and thereby operate to lift the clutch-dog M, in opposition to the stress of its spring 0, out of the notch in in the driving-disk J, thereby leaving said disk and the crank R, which aotuates it, free to continue their movement independently of the pointer until the stroke of the crank is completed. Upon the return-stroke the dog M will so soon as it reaches the notch m automatically drop into it, thereby recoupling the pointer and disk, so that the pointer will be carried back by the movement of the disk under the action of the crank to its first position.

In the operation of the machine the stopindicat-or A is turned by means of its knob E until the figure representing the number to be added and registered by the machine is brought into register with the pointer D. This movement of the indicator A will operate by means of the arm F and friction-roller 7:,revolving wit-h it, to force that one of the stops Gwhieh corresponds with the figure indicated outward, so that its outer end shall project beyond the concentric flange a. The crank R is now to be turned backward to the end of its stroke, so as to carry the pointer 1 of the main indicating-dial Q back to the zeropoint. In this first or backward movement of the crank the disk J, geared to the crank in manner as described, will turn independentl y of the clutch-dog M, which will ride free over the periphery of the disk J until the tie tent reaches the notch m in the disk, whereupon by dropping into said notch it will become coupled to the disk, and during the remainder of the backward stroke of the crank it will be carried with the disk, and will thereby operate to turn the pointer P and also the pawl N of the ratchet-wheel K; but since when moving in this direction the pawl N does not engage the ratchet wheel said wheel and its shaft 11, actuating the adding mechanism, will not be moved. In its adding mechanism.

backward movement the detent U, carried withthe pointer P, will when itreaches the projecting stop G slip freely over it. \Vhen the return or forward stroke of the crank is made, theengagement of the dog M with the disk J willcouple the pointer Pwith the crank and pawl N, so that as the pointer moves forward from the zero-point over the dial the pawl N, in engagement with the ratchet-wheel K, will simultaneously move the adding mechanism in unison therewith So soon, however, as the detent U, carried by the pointer, reaches the stop G it will as it continues to move forward engage said stop, and thereby arrest the further forward move ment of the pointer at a point opposite the figure on the dial Q corresponding with that indicated on the dial of the stop-indicator A. then the pointer is thus arrested, its vibration upon the pivot-pin L as its axis will, by causing said pin to turn, uncouple the clutchdog M from the driving-disk J, and thereby arrest the further movement of the detent N under the influence of said disk, leaving the latter free to move forward independently until the return-stroke of the crank is completed, andpreventing any further movement of the The adding mechanism will thus be actuated only as the pointer P moves from zero to the figure corresponding with the number first selected and indicated by the stop-indicator, and which it was desired to add and register, while the pointer P will remain at the figure last registered to indicate the same until anew number-is added.

As a modification of the stop mechanism, a single-stop lever, as G, Figs. 4 and 5,may be used in place of a series of stops G G G. This lever is curved in semicircular form to partially encircle the pivot B, and is pivoted at about one-third its length to an arm F, projecting radially from the pivot B, so that its ends may swing to and from the pivot B over the periphery of a fixed wheel 10, whose center coincides with the axis of the pivot B. The periphery of this wheel 101s notched at regular intervals, the notches ll 11 11 being made to correspond in number with the figures on the dial A, Fig. 5, and the shorter arm of the curved lever G is fitted with a friction-roller 7t, adapted to ride upon the periphery of the wheel and to rest in its several notches 11 11 11, its contact with the wheel being enforced and maintained by a spring 12. The opposite longer arm of the lever is so shaped and adjusted as that when the friction-roller it drops into one of the stop-notches 11 11 of the-wheel the end of said longer arm will be swung out into position to engage the pawl U, carried by the carrier-plate T in the main indicating mechanism, said carrier-plate being illustrated in Fi 4: as a revolvin dial T whose fi ures are D b 7 D stationary dial Q, as shown in Fig. 1. By

turning the indicator-knob E the stop-lever the outer end of the lever will be swung out into position to arrest the dial T, when the figure corresponding with that indicated on the stop-indicator dial A is brought torview at the sight-opening 13.

In the modification of the invention illus: trated in Figs. 6 and 7 a stationary longitudinal dial or indicating-strip A bearing upon its face figures corresponding with the series of numbers in connection with which the machine is to be used, is substituted for the dial A of Fig. 1, and a pointer D is mounted upon a parallel sliding bar B to move over the indicator. Upon the upper side of this sliding indicator-bar, which corresponds substantially with the rotating shaft B of Fig. 1, is formed an-offset F, inclined or beveled at each end. The bar is carried under a series of vertically-disposed spring-actuated stop-pins G G, corresponding with the numbers on the indicator, and which are mounted in a suitable longitudinal frame C, extending parallel with the indicator-bar and above it. The lower end of each stop is formed with a beveledhead c. The spiral springs b b for the stops are interposed between the two parallel longitudinal plates to and a of the frame. The indicator A is so adjusted with reference to the stops as that when the pointer D is in register with either number on the indicator the offset F on the indicatorbar B will pass under the lower end a of the stop corresponding with the number indicated, and will bear it up, so that the upper end of the stop shall project above the top plate a of the frame. The spindle H for the adding and registering mechanism, and to which the units-wheel H (see Fig. 7) is made fast, is mounted at a right angle with the indicator-bar B and is fitted with a ratchetwheel K, also made fast thereto. A pinion I is mounted to turn loosely upon the spindle H adjacent to the ratchet-wheel K, and is geared to a toothed bar 1 mounted to slide freely parallel with the indicator-bar B so that the movement thereof will produce a revolution of the pinion. A springactuated pawl N is pivoted to the side of the loose pinion 1 to engage the ratchetwheel K in such manner as that it will slide freely over the teeth of the pinion when the pinion is revolved backward, but will as the pinion is turned forward engage the ratchet and cause it to turn in unison therewith.

,Hence amovement in one direction of the toothed bar I will produce a rotation of the spindle H and of the units-wheel fast thereto, while the return movementof the bar will ICO allow the wheel to stand idle. A third longitudinally-sliding bar J 2 is mounted between the indicator-bar B and the bar I actuating the adding mechanism, parallel with said bars and in position to support upon its upper end the free end of a dog M, pivoted to the side of the bar I This detent is free to engage a single notch m in the upperside of the bar J when brought in register with said notch, and otherwise will slide freely upon the bar. The notch and detent are invariably brought into registry when both of the bars I and J are carried to the full end of their outer movement, or movement from the indicator, and so long as the detent remains in the notch the two bars will be coupled thereby to move in unison. The rocking pin L, upon which the dog M oscillates and to which it is secured, is fitted with a radial arm or carrier T, also secured thereto, and which projects vertically upward to afford a bearing for a lateral spring-actuated detent U, pivoted thereto in position to extend over and rest and slide freely upon the upper plate a of the stop-frame C. lience in the reciprocating movements of the bar I the detent U will be carried back and forth in unison therewith over and upon the stopframe 0 in position to contact with either of the stops G, whose end may be projecting above the frame. In moving outward or away from the indicator the detent U will be lifted free over the stop; but in moving inward it will engage and be arrested by the stop. Then this occurs, the resistance of the stop will cause the carrier-arm T and its pivot-pin L to rock, and thereby swing the attached dog M out of its engagement with the bar J {which will be thereby uncoupled from the bar J and left free to continue its movement independently thereof. The bar J is actuated back and forth by means of the toothed segment R engaging a rack on the lower edge of the bar, said segment being operated by the crankarm R and controlled by a double-acting detent S, in a manner as hereinbefore described.

In the operation of this modification of my invention the pointer D is moved to the figure on the indicator-strip A corresponding to the number to be added. This movement will by carrying the offset 1 under the stoppin G corresponding with said number force the pin outward on the frame C. The crankarm R is then to be swung back and forth a full stroke in each direction. As it is moved back the toothed bar J will be moved outward to its full extent. In the outward movement of the bar it will slide independently until the notch m is brought into register with the dog M, resting upon its upper face, whereupon the engagement of the dog with said notch will couple the bar J 2 to the bar I and carry the latter and the detent U, attached thereto, with it to the full end of its outward stroke. As the bar 1 thus moves outward it causes the pinion I to revolve; but since the pawl on said pinion will when moving in that direction ride idly over the ratchet-wheel K it will not move the adding mechanism. So soon, however, as the crankarm begins its return-stroke the pawl N will be brought into active engagement with the ratchet-wheel K, so that the adding mechanism will be actuated by said return movement until the detent U ,sliding on the stopframe O, strikes the projected stoppin, and thereby causes, in manner as described, the dog M to swing out of engagement with the actuating-bar J leaving the craulearm and the bar J actuated by it, to complete their return or inward stroke independently of the bar P, which, with the adding mechanism geared thereto, will come to a standstill. Thus the distance traversed by the bar I upon its inward or return movement from its zero or initial point to the number with which the projected stop corresponds will determine the extent of movement of the adding mechanism at each movement of the crank and will correspond with the number indicated and to be added.
